  • According to the invention, a method for bonding components is provided with the steps:
    • Arranging a first and a second joining part of fiber composite material on a support, wherein an intermediate layer of a fiber composite semifinished product is arranged on the bearing surfaces between the joining parts,
    • Arranging a first tool with a matrix material sprue at the first and the second adherends, such that a first air-tight space for the supply of the matrix material is formed between the first and the second adherends,
    • Arranging a second tool with a suction duct on the first and the second joining part, such that a second airtight space with an opening to the suction duct, which is connected to a vacuum pump, is formed between the first and the second joining part,
    • Production of negative pressure in the region between the first and the second adherends by means of the vacuum pump,
    • Supply of matrix material for infiltration of the intermediate layer into the first space via the matrix material runner,
    • - Hardening of the intermediate layer using pressure and temperature.
  • at the method according to the invention can the semi-finished fiber product of the intermediate layer be mixed with melted yarns, which dissolve under the influence of temperature in the matrix material to to act as a plasticizer. As a matrix material thermosetting resins or ceramic matrix materials are used. The tools can by means of Opposite sealants the parts to be joined be sealed. The tools can be relative to the position the parts to be joined opposite Be arranged pages. The tools can continue as a part be formed. additionally can be an air-permeable and matrix material impermeable Membrane foil between the intermediate layer and the opening to the Suction channel may be arranged.
  • The inventive solution can related to any manufacturing techniques or technologies be applied by fiber composite components, and in particular in Related to techniques such as resin injection method using from negative pressure with liquid Resin or resin films or pre-impregnated plies for fabrication of fiber composite components.
  • The operation of the invention will be described below with reference to the accompanying figure. This shows:
    • - A section through an inventive arrangement of the adherends to be bonded with the intermediate layer used in the invention and with the tools used in the invention.
  • Under The term "infiltration" is introduced according to the invention understood by matrix material in fiber composite semi-finished products. In particular, will the term "infiltration" in the following for the inventively provided Introduction of the matrix material under application of negative pressure (suction) or by using only a slight overpressure on the resin reservoir uses.
  • The figure shows as an embodiment of the invention an arrangement of a first 1 and a second one 2 Joining part, which are preferably formed from fiber composite material, on a support 11 Generally, the joining parts 1 . 2 also be formed from other solid materials, such as stone, wood, plastic or metal. Between the parts to be joined or at the bearing surfaces is an intermediate layer 4 arranged from a fiber composite semi-finished product.
  • The term "fiber composite semifinished product" in the context of the invention, the material or to be infiltrated intermediate layer of reinforcing fibers (eg carbon, aramid, glass fibers) understood, from which after an infiltration of matrix material and after curing of the matrix material, a fiber composite connecting the Fügeteile Layer can be produced. The matrix material stabilizes the intermediate layer after it has hardened and additionally ensures the mechanical connection of the intermediate layer 4 to the mutually facing bearing surfaces of the joining parts. The fiber composite semifinished product or the intermediate layer 4 For example, it may be constructed of textile structures such as woven, laid, multiaxial, embroidered, knitted, braided and knit. The textile structures may be connected by suitable methods such as sewing and gluing.
  • In order to ensure the reproducibility of the mechanical strength of the adhesive bond, the fiber volume content of importance. The in the adhesive gap, ie between the bearing surfaces of the joining parts 1 . 2 To be introduced textile of reinforcing fibers must ensure this. This becomes problematic when it is not possible to set a constant gap between the two joining surfaces of the two parts to be joined. In practice, this situation is much more likely than the ideal condition of a constant distance between the two parts to be joined. The textile to be introduced into the intermediate layer should fill this gap completely, despite the variation of the gap width, and should not make the fiber volume content even at the narrowest points too high.
  • strongly Different gap thicknesses can be achieved by adding additional locally Balancing textile layers.
  • A different possibility is to use a textile with high elasticity. For example, knitwear let yourself strongly stretching while reducing its thickness. This effect the transverse contraction of the textile is exploited to be in all places of the Joining surface, adapted to the local Gap thickness, the desired Set fiber amount. For this, the elastic textile in the gap subject to stretching and when springing back it fills the place exactly the local Gap thickness lets him. In this way, an approximately constant fiber density is formed in the gap and thus reproducible conditions.

The infiltration ability is linked to its viscosity properties, which in turn determines the maximum infiltration pathway. In the present invention, epoxy resins are preferably used as the matrix material, but other thermosetting resins may be used, for example, phenolic resins, bismaleimides, polyester resins or low-viscosity adhesives. In principle, it is also possible to use a matrix material that can be ceramized together with the two parts to be joined.
